This package makes it possible to insert a "before" and "after" picture. The images are mapped onto eachother and with a mouse slider visualize the before and after effects of the two images. This add-on works responsive and also works on mobile touch devices.
This add-on is especially good for dentists to show before and after images of their work. Other places where this would make sense would be everybody who wants to show the progress from old to new. Fx. painting cars, winter summer, renovating houses and so on.
